# Quais são os números de oxidação do carbono no monóxido de carbono e no metanol?

#### Responda:

Nós temos :stackrel(II^+)C-=O contra H_3stackrel(II^-)COH, então o metanol tem o carbono com o menor estado de oxidação.

#### Explicação:

A soma do números de oxidação é igual à carga na molécula e as duas moléculas são neutras.

Aqui estão algumas regras que não precisam ser lembradas, mas precisam ser usadas implicitamente.

1. "The oxidation number of a free element is always 0."

2. "The oxidation number of a mono-atomic ion is equal" "to the charge of the ion."

3. "For a given bond, X-Y, the bond is split to give "X^+ "and" Y^-, "where Y is more electronegative than X."

4. "The oxidation number of H is +1, but it is -1 in when" "combined with less electronegative elements."

5. "The oxidation number of O in its" compostos "is usually -2, but it is -1 in peroxides."

6. "The oxidation number of a Group 1 element in a" "compound is +1."

7. "The oxidation number of a Group 2 element in a" "compound is +2."

8. "The oxidation number of a Group 17 element in a binary" "compound is -1."

"9." "The SUM of the oxidation numbers of all of the" "atoms in a neutral compound is ZERO."

10. "The SUM of the oxidation numbers in a polyatomic ion" "is equal to the charge of the ion."
